What happens to pyruvate during alcohol fermentation?
During alcohol fermentation, pyruvate, produced from glycolysis, is converted into ethanol and carbon dioxide. This process occurs in anaerobic conditions, where the pyruvate is first decarboxylated to form acetaldehyde, which is then reduced to ethanol by the enzyme alcohol dehydrogenase. This conversion regenerates NAD+, allowing glycolysis to continue and produce ATP in the absence of oxygen.
What happens to a glucose molecule when glycolysis occurs?
During Glycolysis, Glucosemolecules are split into two pyruvates during a sequence of enzyme-controlled reactions. This occurs in both aerobic and anaerobic respiration.
Glycolysis results in the production of?
Glycolysis results in the production of ATP (Adenosine triphosphate), NADH, and pyruvate. This process breaks down glucose into smaller molecules, generating energy in the form of ATP along with reducing equivalents in the form of NADH.
How many molecules of ATP does fermentation yield?
During glycolysis it makes a net amount of 2 molecules of ATP. Fermentation happens anaerobically (without oxygen) and the reduction of pyruvate into lactate itself does not yield any ATP. But I think the answer you are looking for is 2 ATP.
What happens after glycolysis during cell respiration?
The 2 pyruvate molecules created in Glycolysis are oxidised to form Acytl-CoA. This then enters the Citric Acid Cycle. After the Citric Acid Cycle comes the electron-transfer chain, which is where the majority of ATP are produced during respiration.
What happens during glycosis in cellular respiration?
During glycolysis, which occurs in the cytoplasm of the cell, one molecule of glucose is broken down into two molecules of pyruvate. This process involves a series of ten enzymatic reactions that convert glucose into pyruvate while producing a net gain of two ATP molecules and two NADH molecules. Glycolysis does not require oxygen, making it an anaerobic process, and it serves as the first step in both aerobic and anaerobic respiration. The pyruvate produced can then enter the mitochondria for further processing in aerobic respiration or be converted into lactate or ethanol in anaerobic conditions.

What happens to pyruvate produced when very little oxygen is available?
Pyruvate is the result of glycolysis, the degradation of a molecule of glucose. In aerobic conditions (with O2 present), pyruvate is oxidized to H2O and CO2 via the citric acid cycle and oxidative phosphorylation to produce energy (ATP). In anaerobic conditions (low levels of O2), pyruvate metabolism goes in two directions: in yeasts, an alcoholic fermentation takes place (with the production of two CO2 molecules + two molecules of ethanol); while in muscle, homolactic fermentation occurs (with the result of 2 molecules of lactate).
Where does glycolysis happens?
Glycolysis occurs in the cytoplasm of the cell. It is the first step in cellular respiration and involves the breakdown of glucose into pyruvate, producing ATP and NADH in the process.
Do plants undergo glycolysis?
No, plants do not undergo glycolysis. Glycolysis is a metabolic process that occurs in the cytoplasm of cells to break down glucose into pyruvate. In plants, glycolysis occurs in the cytoplasm of plant cells just like in animal cells.
What happens during glycloysis in celluar respiration?
Glycolysis is the first step of cellular respiration, occurring in the cytoplasm of the cell. During this process, one glucose molecule is broken down into two molecules of pyruvate, producing a net gain of two ATP (energy) and two NADH (electron carrier) molecules. The process involves a series of enzymatic reactions that convert glucose into intermediates and ultimately pyruvate, while also releasing a small amount of energy. Glycolysis is anaerobic, meaning it does not require oxygen.
What is the net number of ATP produced in glycolysis?
During glycolysis it makes a net amount of 2 molecules of ATP. Fermentation happens anaerobically (without oxygen) and the reduction of pyruvate into lactate itself does not yield any ATP. But I think the answer you are looking for is 2 ATP.
